Troubleshooting and fault elimination

If any malfunctions should occur during operations, please check for possible causes based on the following 
table. If the fault cannot be fixed or eliminated by one of the listed measures, please contact customer ser-
vice.

Fault

Cause

Remedy

Brake cannot be released, 
air gap is not zero

Coil interruption

❚

Measure the coil resistance using a multimeter:
- If resistance is too high, replace the complete spring-

applied brake.

Coil has contact to earth or 
between windings

❚

Measure the coil resistance using a multimeter:
- Compare the measured resistance with the nominal 

resistance. Refer to 

 19 for the values. If resist-

ance is too low, replace the complete stator.

❚

Check the coil for short to ground using a multimeter:
- If there is a short to ground, replace the complete 

spring-applied brake.

❚

Check the brake voltage (refer to section on defective 
rectifier, voltage too low).

Wiring defective or wrong

❚

Check the wiring and correct.

❚

Check the cable for continuity using a multimeter:
- Replace defective cable.

Rectifier defective or incorrect

❚

Measure rectifier DC voltage using a multimeter.

If DC voltage is zero:

❚

Check AC rectifier voltage. 

If AC voltage is zero:

- Switch on power supply.
- Check fuse.
- Check wiring.

If AC voltage is OK:

- Check rectifier.
- Replace the defective rectifier.
- Diode is defective; use a suitable new rectifier.

❚

Check the coil for winding short or ground short.

❚

If the rectifier defect occurs again, replace the entire 
spring-applied brake, even if you cannot find any fault 
between turns or short circuit to ground. The error may 
only occur on warming up.

Brake cannot be released, 
air gap is not zero

Incorrect micro-switch wiring

Check the wiring of the micro-switch and correct it.

Micro-switch incorrectly set

Replace the complete stator and make a complaint about 
the setting of the microswitch to the manufacturer.

Air gap "s

L

" is too large

Adjust the air gap: 

 60.
